Times like these are why a lot of people praise the spot & "chill" mentality/approach.
#$BTC is still having a good Q4 so far and is simply giving back some of its post election gains.
Obviously, a lot of alts have done worse, but some have done better. It's why I also prefer to have my base portfolio consist of mostly #$BTC & #$ETH and have alts on the side.
If you've been trading this on leverage its likely you've taken a larger hit. If you're emotional about the loss, this is not the time to revenge trade it back. That's where a lot of people go bust during these corrections.
Generally you want to let the market calm down and form some kind of consolidation or range after which you can re-assess.
There will be plenty of opportunities out there, no need to make it all at this very moment.
